1. High quality material: M35 cobalt. Added 5% cobalt to improve hardness and heat resistance. The Rockwell hardness is up to 67. It has a faster cutting speed and a longer service life, which is 12 times that of an average HSS bit.
2. Accurate Card Position: Self-centering. The guiding separation point of the 135° rapid cutting is automatically centered and can be penetrated quickly under a small pressure. The straight shank can be firmly fixed and accurately centered, suitable for standard drill trays and conventional circular trays.
3. Efficient and fast: High-efficiency drilling can be carried out without walking. Remove debris and particles faster and easier.
4. Low cost: The lowest cost of drilling each hole. The solid cobalt steel drill bit can be reground.
5. Split point: You can drill directly to the required size without pre-drilling
6. Widely used: Suitable for drilling stainless steel, copper cast iron, galvanized pipe, iron, aluminum alloy and other non-heat-treated metals whose hardness is less than HRC38. Not suitable for hardened steel/high carbon steel. If it cannot penetrate, try to adjust the speed.

Dobri su boreri oštri pomalo nauljiti, mislim da nisu profi ali dobra je bila cijena, popunio sam neke setove borera, na poslu i i u jednom drugom pogonu i jedan set koji je više manje kompletan, koji mi je doma kad zatreba, dosta su oštri ali mislim da nisu profi boreri, prije sam isto uzimao borere od Bangoda mislim na setove, ovdje nema nekih dimenzija, neki dan sam pilu za drvo bušio, to je tvrdi materijal jednu rupu i tupi su, nemože dalje, bio je tvrd materijal tj. otvrđeni materijal, ima i kod nas za kupiti ali budu malo skuplji, a s ovima sam popunjavao tri seta, lim vijci recimo trebaš ga probušiti iči če do neke mjere i brzo zatupi, iako piše kolbat mislim da je kao HSS koji možda nije iz Kine, moguće da profesionalac neče htjeti možda za ako mu slučajno zatreba, mislim da je kvaliteta tih stvari otpala do neke mjere, bolji su pet puta nego od Kauflanda i Lidla koji mogu biti opasni kad puknu i mogu frcnuti, m42 boreri od Banggooda su još bolji, Thanks Banggood
Ár-értékben jó termék.
